Google is your friend:
Manual: https%3A%2F%2Fdiagramas.diagramasde.com%2Fotros2%2 FKV-34DRC510.pdf (first hit with a google search for the Service Manual part number, 9-965-937-02) That's for the DA-4, multiple models. Most Sony CRT sets have the same data acronyms: VFRE Vertical Frequency VPOS Vertical Picture Position VSIZ Vertical Picture Size VLIN Vertical Picture Linearity VSCO Vertical Correction VCOM Vertical Compensation VUSN Shrinks Vertical Height to 16x9 Area VZOM Places Bars on Picture to give 16x9 Area EHT Adjust Height of VZOM ASP Vertical Picture Size - Aspect SCRL Vertical Picture Position Can't stress this enough - write down ALL initial values before making any adjustment. Note the range of values too - and don't go above or below. If you do, you may briick the set, as Sony used the DAS device to recover/restore EEPROM data. Without it, you're gonna be SOL if you corrupt the EEPROM Also, on the HD CRT sets, try the customer menu setting for aspect first - don't try to feed a 4:3 with a 16:9 aspect selected (or any other movie aspect ratio!)

I downloaded the service manual yesterday. Don't see vlin anywhere. The tv is a 4:3 tube. It's not the wide-screen model.

Ok I figured it out. Using 2 and 5, I went down to VPOS, the using 1 and 4, I went to VLIN. Here I a couple hours, I'll connect everything again and change the vlin 1 or 2. I'll update after.

Ok, I went in to VLIN which is default at 9. I went down to 7. No change. I went up to 11. No change. I don't know what's going on

Could it be a different setting? Is it possible it's not something to with service mode?
